> Currently, {{KILLED}} state in SubQuery does not handle any event. As I mentioned in TAJO-1111, {{QueryUnit}} in even terminal states may receive additional unexpected events from a running tasks because a running task reporter sends a progress periodically; that is the report is not synchronized with a task life cycle. As a result, When a killed {{QueryUnit}} receives unexpected events, it can cause some event towards {{SubQuery}}. But, {{SubQuery}} does not handle any addition events if {{SubQuery}} is already in {{KILLED}}.
> This patch adds some transitions to SubQuery in order to fix the above problem.
